TO HENRY SILO-BRACING.

Specification of Letters Patent.

Application filedFebruary 14, 1914. Serial No. 818,808.

To aZZ whom it may concern Be it known that I, FREDOLIEN J. O'BERER, a citizen of the United States, and a resident of the city of Portland, county of have invented silos built of staves it is well known that they have a tendency to become twisted to such extent as to bring the staves in more or less oblique position; the staves movinglongitudinally against each other. This condition is brought .about by the pressure of the wind against the silo; and when in this condition it is no longer fit for service. The

. bracing means heretofore generally used consisted of guy wires attached to the up er portions of a $110 and extending outwar ly, in radial form, to some distant point where the ends of the guy wires are fastened to the ground. This form of. bracing is adapt- 'ed only to prevent the silo from tipping and falling over. However, it has been found that a silo will not fall over under any but extraordinary circumstances, but instead will fall by twisting; and twisting is not prevented by guy. wires arranged as mentioned. The guy wires have another objection in this, that they are frequentlyinthe way; and, besides, cattle rub against them, in so doing causing the silo to rock, thereby creating a tendency for the silo to get out of shape.

The object of my invention is to provide simple, durable and efficient bracing means for holding the silo firmly on its foundation -and prevent any twisting action; also to keep all the bracing elements close to the sides of the silo.

'I attain my object by bracing elements constructed and arranged as hereinafter described.

In the accompanying drawings: Figure l is a side elevation showing the foundation and body of my silo braced and held in place by my improved bracing means; the roof is omitted, only a part of one of the rafters being shown, but it is understood that the roof construction may be of similar construction to that described in my application tremities of which are threaded.

for Letters Patent filed January 8, 1914 under Serial No. 811,112 entitled: An im- Patented Mar. 23, 1915.

provement in silo, and Figs. 2 and 3 are details of construction.

The foundation, a, may be of concrete, the silo body, 6, is built of staves. In the foundation are anchored anchor rods, 0, the ex- On such extremities are placed double sleeves d. In one member of such sleeves is aflixed one extremity of the anchor rod 0, said sleeve being locked in place by a nut e, threaded onsaid extremity of the anchor rod. In

the other member of said sleeve is placed a brace-rod 7, having a nut g, threaded on its extremity. The upper ends of the brace rods 7 are inserted in one member of a double sleeve it; the upper extremity of the brace-rod 7 having a nut, threaded'thereon. In the companion member of said sleeve it is'inserted the lower end of the'brace-rod j, on the; extremity of which is threaded a nut is. The upper end of the brace-rod j is inserted in a perforated lug Z, integral with the clamping bars m, the latter bearing on'a bearing cap,'z', set on the top rim of the body 6. The clamping bars, m, are located at the sides and body, and are made with two lugs, Z, Z, as shown in Fig. 2, for receiving the upper ends of the brace-rods j, which ends are secured in bars m are located at either side of the door frame 0 (as shown in Fig. 1) and. these clamping bars are made with only a single lug p (as shown in Fig. 3) for the upper end of one brace-rod 7''. Each of the clamping-bars m or m is made with a lip q for holding it against being pulled 03, and it is bolted in place by a bolt and nut, 1', s,- the bolt being inserted through the clam ing the rear of the silo I v place by nuts 11,. The clamping;

bar, the bearing cap, 2', and a stave o the shown' in Fig. 1, and are arranged to run in opposite directions so as to brace both ways, As many brace-rods as desired may be used, The tightening of the brace-rods is readily accomplished by the proper .ad-

justment of the nuts on the ends of the brace rods inserted in the double sleeves k.

t represents a portion of one of the rafters of the roof, the details of construction of the roof, however, are immaterial. In building my improved silo I build the same with a roof as described in my previously filed application for patent, above referred to.

From the description given it Will noW be apparent that the brace-rods not only hold the silo firmly in place on its foundation, but also render it impossible for the silo to-twist in any direction. The brace rods also serve as effective lateral bracing means and .rigidly hold the silo against tipping over or even tilting.

I claim:

1. The combination With a foundation and a container formed of staves, thereon mounted, of a holding element seated on a plurality of adjacent staves, being fastened to one thereof and permitting relative movement to the other staves under the holding means, and brace rods arranged helically and in opposite directions around the body of the container, said brace rods being fastened at their extremities to the foundation and to said holding means.

' container, said brace rods being fastened at their extremities to the foundation and to said holding means, and means for relatively shortening the brace rods.

3. The combination with a foundation ing caps and the foundation, said brace rods being arranged helically and in opposite directions around the body of the container.

4. The combination with a foundation and a container, formed of staves, thereon 1nounted,'of a plurality of channel-like bear ing-caps seated on the rim of the container and extending over a series of adj acent stavcs,

said bearing-caps being connected with one stave of said series of staves on Which they are seated, and the others of said series being permitted free lateral movement relative to said bearing-caps, clamp-plates, fixed on the bearing caps, said clamp-plates having lateral inclined ears; anchors fastened in the foundation, and adjustable counter/brace rods arranged helically and in. opposite directions around the container, said bracerods connecting said clamp plates to said anchors:
